CVE-2026-39848Network attack vector

Container start or stop via CSRF

Published Apr 9, 2026 · Updated Apr 9, 2026

CSRF in Dockyard before 1.1.0 allows remote attackers to start or stop Docker containers through an administrator's browser. The /apps/action.php endpoint accepts action and container-name parameters in state-changing GET requests without a CSRF token or equivalent request validation. A logged-in administrator must be induced to load a crafted request; the selected container then starts or stops under the administrator's session.
